Abstract

1300135 Coating with metal powder BRITISH STEEL CORP 19 April 1971 [3 March 1970] 10190/70 Heading C7D A metallic substrate is coated with a metal powder of particle size not exceeding 40 microns, the metal powder including a siliceous substance which facilitates its flow. The metal powder may be Al, Mg, Ni, Zn, Cu, Db, Cu/Zn, Al/Zn, Al/Fe or Zn/Fe. A steel sheet 1 is preliminarily treated by degreasing in sodium orthosilicate 4, pickling in HCl 6, and electroplating with Fe from a FeCl 2 bath 11. The strip 1 is washed at 5, 10 and 12 and dried at 13. At a station 16, sodium or potassium silicate is spread on to one surface 2 of the strip 1. Powdered aluminium as a coatant is spread from a hopper 18 by a vibratory spreader 17 on to the surface 2. The Al powder contains 0À0001% wt of silica particles which have been rendered hydrophobic e.g. with a coating of an organic hydrophobic substance. The reverse side 3 of the strip is similarly coated at stations 22, 23, 24 and the strip dried at 25. Sodium carboxymethylcellulose is dispersed on to both sides 2, 3 of the strip at 26, 27 and the strip again dried at 30 before passing through compression rolls 31, 32 to consolidate the coating. The coated strip is heat-treated at 500‹C for one hour or 350‹C for 15 hours. When coating steel strip with nickel, the strip is electrolytically coated with Ni, and a coating powder of Ni with 0À05% wt SiO 2 employed. The drier 30 heats the strip to 200‹C and heat treatment comprises heating in a reducing atmosphere (95% vol N 2 , 5% vol H 2 ) for 16-20 hours at 700-750‹C.
